x86/cpu: Fix the AMD Fam 17h, Fam 19h, Zen2 and Zen4 MSR enumerations
The comments introduced in <asm/msr-index.h> in the merge conflict fixup in:
8f4156d58713 ("Merge branch 'x86/urgent' into perf/core, to resolve conflict")
... aren't right: AMD naming schemes are more complex than implied,
family 0x17 is Zen1 and 2, family 0x19 is spread around Zen 3 and 4.
So there's indeed four separate MSR namespaces for:
MSR_F17H_
MSR_F19H_
MSR_ZEN2_
MSR_ZEN4_
... and the namespaces cannot be merged.
Fix it up. No change in functionality.
